  • Update technical documentation

• Days 4-5: Deployment

  • Set up production environment
  • Configure database for production
  • Set up backup system
  • Configure error logging for production
  • Perform final testing in production environment

Development Approach

Iterative Development

• Each feature will be developed following these steps:
  1. Implement entity and repository classes
  2. Implement service layer with business logic
  3. Implement controller with routes
  4. Create templates and UI components
  5. Write tests
  6. Review and refine

Testing Strategy

• Unit tests for all entity, repository, and service classes
• Feature tests for controllers and UI flows
• Integration tests for database operations
• Manual testing for UI and user experience

Code Quality Assurance

• Follow PSR coding standards
• Use static analysis tools (PHPStan, Rector)
• Conduct code reviews
• Maintain high test coverage

Risk Management

Potential Risks and Mitigation Strategies

• Scope Creep: Strictly adhere to the defined requirements and manage change requests
• Technical Challenges: Allocate additional time for complex features
• Integration Issues: Implement comprehensive integration testing
• Performance Issues: Conduct performance testing early and optimize as needed

Conclusion

This implementation plan provides a structured approach to developing the Drinks Inventory System over a 6-week period. The phased approach allows for incremental development and testing, ensuring that each component is properly implemented and integrated before moving on to the next phase.
